1. Iphedi eyiliweyo kufuneka ikwazi ukukhawulelana neemfuno zobungakanani bobude, ububanzi kunye nesithuba sephinikhodi yesixhobo ekujoliswe kuso.
Ingqwalasela ekhethekileyo kufuneka ihlawulwe: impazamo ye-dimensional eyenziwa yi-pin yesixhobo ngokwayo kufuneka ithathelwe ingqalelo kuyilo - ngakumbi izixhobo ezichanekileyo kunye neenkcukacha kunye nezixhumi.

Ngaphandle koko, kunokukhokelela kwiibhetshi ezahlukeneyo zohlobo olufanayo lwezixhobo, ngamanye amaxesha isivuno se-welding processing siphezulu, ngamanye amaxesha iingxaki ezinkulu zemveliso zenzeka!

Ke ngoko, uyilo oluhambelanayo lwephedi (elufanelekileyo kwaye luqhelekile kuninzi loyilo lwepedi yesixhobo sabavelisi abakhulu) lubaluleke kakhulu!

Ngokumalunga neli nqaku, ezona mfuno zilula kunye neendlela zokuhlola zezi:

Beka eyona sixhobo ekujoliswe kuyo kwiphedi yebhodi ye-PCB ukuze iqwalaselwe, ukuba isikhonkwane ngasinye sesixhobo sikwindawo yepadi ehambelanayo.

Uyilo lwephakheji yale pad ayiyongxaki enkulu.Ngakolunye uhlangothi, ukuba ezinye izikhonkwane azikho kwi-pad, ayilungile.

2. Iphedi eyilelweyo kufuneka ibe nophawu olucacileyo lwesalathiso, kukhethwa ukuba ibe luphawu lwepolarity olwe jikelele kunye nokwahlulakala lula.Ngaphandle koko, xa kungekho sampuli ye-PCBA eqinisekisiweyo yereferensi, ukuba umntu wesithathu (ifektri ye-SMT okanye i-private outsourcing) yenza inkqubo ye-welding, iya kuba yinto enokuthambekela ekubuyiseleni i-polarity kunye ne-welding engalunganga!

3. Iphedi eyiliweyo kufuneka ikwazi ukuhlangabezana neeparamitha zokucubungula, iimfuno kunye nobugcisa befektri ethile yesekethe yePCB ngokwayo.

Umzekelo, ubungakanani bomgca wephedi, isithuba somgca, ubude bomlinganiswa kunye nobubanzi obunokuyilwa, njl. Ukuba ubungakanani bePCB bukhulu, kuyacetyiswa ukuba uyile ngokwenkqubo yefektri yePCB edumileyo neqhelekileyo kwimarike, ukuze xa umboneleli we-PCB etshintshwa ngenxa yomgangatho okanye imiba yentsebenziswano yeshishini, bambalwa kakhulu abavelisi bePCB abanokukhetha kuzo kwaye ishedyuli yemveliso ilibazisekile.
